(2) Tightening torque indication (See Fig. 11)
The tightening torque differs depending on the
type of screw and the material being tightened.
The unit indicates the tightening torque with the
numbers “1, 3, 5 ... 22” on the clutch dial, and a
dot. The tightening torque at position “1” is the
weakest and the torque is strongest at the highest
number.
(3) Adjusting the tightening torque (See Fig. 11)
Rotate the clutch dial and line up the numbers “1,
3, 5, ... 22” on the clutch dial, or the dot, with the
triangle mark on the outer body. Adjust the clutch
dial in the weak or the strong torque direction
according to the torque you need.
CAUTION:
●
The motor rotation may be locked to cease while
the unit is used as drill. While operating the driver
drill, take care not to lock the motor.
●
When setting the shift knob to “HIGH” (high
speed) and the position of the clutch dial is “17”
to “22”, it may happen that the clutch does not
engaged and that the motor is locked. In such a
case, please set the shift knob to “LOW” (low
speed).
●
If the motor is locked, immediately turn the power
off. If the motor is locked for a while, the motor or
battery may be burnt.
●
Too long hammering may cause the screw broken
due to excessive tightening.
●
A buzzing noise is produced when the motor is
about to rotate; This is only a noise, not a machine
failure.
